When I try to use "move window to next monitor" or "move window to next monitor and size proportionally" the window just flicks to the right side of my main (4k) monitor and shrinks. It continues to shrink further if I use the function again.

It will, however, work in the other direction, and will put the window from the 1080 monitor to the 4k, but it only works in that direction.

This is a big problem for me as I use this function all the time.
